Python Order of operations

r=11; y=2.5; c=4 වශයෙන් r, y, c විචල්‍යවලට අගය පවරා ඇත.

ඒ අනුව, r%3*c+10/y යන පයිතන් ප‍්‍රකාශයේ නිවැරත්‍ථ අගය කුමක් ද?


(1) 6.2 (2) 8.0 (3) 12.0 (4) 24.0 (5) 40.0

command	name	example	output
+	Addition	4+5	9
-	Subtraction	8-5	3
*	Multiplication	4*5	20
/	Division	19/3	6
%	Remainder	19%3	5
**	Exponent	2**4	16

The order of operations

1. parentheses ()
2. exponents **
3. multiplication *, division \, and remainder %
4. addition + and subtraction -

 Multiplication (*) and modulo operator (%) have the same precedence, so you evaluate from left to right for this example 

r%3*c+10/y 
((r% 3)*c)+(10/y)
((11% 3)*4)+(10/2.5)
(2*4)+(4)
12

All operators

+       -       *       **      /       //      %
<<      >>      &       |       ^       ~
<       >       <=      >=      ==      !=

 
100 - 25 * 3 % 4 the result is 97 how?

25*3 = 75
75 % 4 = 3 (4*18 = 72; remainder is 3)
100 - 3 = 97

Operator	Description	Example
+, -	Addition, Subtraction	10 -3
*, /, %	Multiplication, Division, Modulo	27 % 7 Result: 6
//	Truncation Division (also known as floordivision) The result of the division is truncated to an integer. Works for integers and floating-point numbers as well	27 % 7 Result: 6
+x, -x	Unary minus and Unary plus (Algebraic signs)	-3
~x	Bitwise negation	~3 - 4 Result: -8
**	Exponentiation	10 ** 3 Result: 1000
or, and, not	Boolean Or, Boolean And, Boolean Not	(a or b) and c
in	"Element of"	1 in [3, 2, 1]
<, <=, >, >=, !=, ==	The usual comparison operators	2 <= 3
|, &, ^	Bitwise Or, Bitwise And, Bitwise XOR	6 ^ 3
<<, >>	Shift Operatoren	6 << 3
